Malfunction Description Corrective action
E rror of sensor T5L(lower water temperature sensor)
E 1
Maybe the connection between sensor and PCB is
broken or sensor has been broken.
Contact a qualified person to service the unit.
Tank and wired controller communication error
E 2
The connection between controller and PCB is
broken or PCB has been broken.
E vaporator temperature sensor T3 error
E 4
The connection between sensor and PCB is
broken or sensor has been broken.
Contact a qualified person to service the unit.
Ambient temperature sensor T4 error
E 5
The connection between sensor and PCB is
broken or sensor has been broken.
Contact a qualified person to service the unit.
Compressor discharge temperature sensor TP error
E 6
The connection between sensor and PCB is
broken or sensor has been broken.
Contact a qualified person to service the unit.
E 8
Some wires have been broken or bad wiring
connection.
Contact a qualified person to service the unit.
If PCB current_induction_circuit check the current
difference between L,N >14mA, system consider it as
"electric leakage error"
E lectric leakage error
Compressor suction temperature sensor TH error
E 9
The connection between sensor and PCB is
broken or sensor has been broken.
Contact a qualified person to service the unit.
E -heater open-circuit protection (I E H(Current difference
E -heater on & e-heater off )<1A)
Maybe the E -heater has been broken or bad wiring
connection after repair.
P2
High discharge temperature protection
Tp>115
℃ , Protection active
Tp<90 ℃ , Protection inactive
System blocked, air or water or low
refrigerant(leakage) in system (after repair), water
temperature sensor malfunction, etc.
Contact a qualified person to service the unit.
Compressor overloaded protection (10 secs after
compressor start up), Current checking starts ,
1)only compressor running, if it is >7A , the
compressor will be stopped and protected.
2)Come-heater opend, if it is >I E H+7,the
compressor will be stopped and protected.
Compressor broken, system blocked,
air or water or too much refrigerant in system (after
repair), water temperature sensor malfunction, etc.
℃
When the ambient temp T4 is out of Heat Pump
running range (5
～ 43
℃
) Heat Pump will stop, unit will
show LA on the position of clock on display until T4
back to (5
～ 43 ).
It is normal, and not necessary to repair.
